Abstract Background The last five decades have seen a surge in viral outbreaks, particularly in tropical and subtropical regions like Brazil, where endemic arboviruses such as Dengue (DENV), Zika (ZIKV), and Chikungunya (CHIKV) pose significant threats. However, current diagnostic strategies exhibit limitations, leading to gaps in infection screening, arbovirus differential diagnoses, DENV serotyping, and life-long infection tracking. This deficiency impedes critical information availability regarding an individual's current infection and past infection history, disease risk assessment, vaccination needs, and policy formulation. Additionally, the availability of point-of-care diagnostics and knowledge regarding immune profiles at the time of infection are crucial considerations. Objectives This review underscores the urgent need to strengthen diagnostic methods for arboviruses in Brazil and emphasizes the importance of data collection to inform public health policies for improved diagnostics, surveillance, and policy formulation. Methods We evaluated the diagnostic landscape for arboviral infections in Brazil, focusing on tailored, validated methods. We assessed diagnostic methods available for sensitivity and specificity metrics in the context of Brazil. Results Our review identifies high-sensitivity, high-specificity diagnostic methods for arboviruses and co-infections. Grifols transcription-mediated amplification assays are recommended for DENV, CHIKV, and ZIKV screening, while IgG/IgM ELISA assays outperform Rapid Diagnostic Tests (RDTs). The Triplex real-time RT-PCR assay is recommended for molecular screening due to its sensitivity and specificity. Conclusion Enhanced diagnostic methods, on-going screening, and tracking are urgently needed in Brazil to capture the complex landscape of arboviral infections in the country. Recommendations include nationwide arbovirus differential diagnosis for DENV, ZIKV, and CHIKV, along with increased DENV serotyping, and lifelong infection tracking to combat enduring viral threats and reduce severe presentations.
ABSTRACT
Abstract Background: Arboviral diseases are a group of infectious diseases caused by viruses transmitted by arthropods, mainly mosquitoes. These diseases, such as those caused by the dengue (DENV), Zika (ZIKV), chikungunya (CHIKV), and yellow fever (YFV) viruses, have a significant impact worldwide. In this context, entomological surveillance plays a crucial role in the control and prevention of arboviruses by providing essential information on the presence, distribution, and activity of vector mosquitoes. Based on entomological surveillance, transovarian transmission provides information regarding the maintenance and dissemination of arboviruses. The objective of this study was to detect these arboviruses in Goiânia, Goiás, and analyze the occurrence of transovarian transmission. Methods: Aedes aegypti eggs were collected from different regions of Goiânia and cultivated under controlled laboratory conditions until the emergence of adult mosquitoes. Adult females were grouped into pools containing their heads and thoraxes. These pools were subsequently evaluated using reverse-transcription quantitative polymerase chain reaction (RT-qPCR) assay. Results: A total of 157 pools (N=1570) were analyzed, with two pools testing positive for CHIKV and one pool testing positive for ZIKV, indicating that the offspring resulting from transovarian transmission are potentially infectious. Conclusions: In summary, the demonstration of the vertical transmission mechanisms of CHIKV and ZIKV in A. aegypti serves as an alert to health authorities, as these diseases are still underreported, and their primary urban vector has likely acquired this capacity, contributing to the dissemination of these infections.
ABSTRACT
OBJECTIVES We report the first case of Oropouche fever detected in the border region of Colombia. METHODS Using a multiplex real-time polymerase chain reaction (PCR), genetic sequencing and clinical characteristics during the dengue epidemic in 2019, a total of 175 samples were analysed, from cases notified to the system epidemiological surveillance such as dengue. FINDINGS The Oropouche virus (OROV) isolate from Leticia belongs to lineage 2 according to both M and S genome segments maximum likelihood (ML) analysis, shares a common ancestor with samples obtained in Esmeraldas, Ecuador and Turbaco, Colombia. The patient: a woman resident in the border neighbourhood of the municipality of Leticia had the following symptoms: fever, headache, retro-orbital pain and myalgias. MAIN CONCLUSION This cross-border surveillance can be useful to give an alert about the entry or exit of arboviruses circulation in the region, which are often underreported in public health surveillance systems.
ABSTRACT
ABSTRACT Objective: To analyze the factors associated with the individual use of insect repellent by women of childbearing age living in area endemic for arboviruses in Fortaleza, Brazil. Methods: This is a cohort study carried out between 2018 and 2019 with women aged between 15 and 39 years in Fortaleza, state of Ceará, Brazil. A total of 1,173 women users of one of the four selected primary health care units participated in the study. The outcome was divided into: continued use, discontinued use, and nonuse of insect repellent. Crude and adjusted multinominal logistic regression analysis was carried out guided by a hierarchical model, with presentation of the respective odds ratio (OR) and 95% confidence intervals (95%CI). The independent variables include: socioeconomic and demographic data, environmental and sanitary characteristics, knowledge of the insect repellent, and behavioral and pregnancy-related aspects. Results: Only 28% of the participants reported using insect repellent during the two waves of the cohort. Women with higher education (OR=2.55; 95%CI 1.44-4.51); who are employed (OR=1.51; 95%CI 1.12-2.03); who received guidance from healthcare professionals (OR=1.74; 95%CI 1.28-2.36) and the media (OR=1.43; 95%CI 1.01-2.02); who intensified precautions against mosquitoes during the epidemic (OR=3.64; 95%CI 2.29-5.78); and who were pregnant between 2016 and 2019 (OR=2.80; 95%CI 1.83-4.30) had increased odds for continued use of insect repellent. Conclusion: The use of insect repellent among women of childbearing age was associated with a higher level of education, employment, guidance on insect repellent provided by healthcare professionals and the media, behavioral changes to protect against mosquitoes during the Zika virus epidemic, and pregnancy when occurring as of the beginning of the epidemic period.
RESUMO Objetivo: Analisar os fatores associados ao uso de repelente individual por mulheres em idade fértil residentes em área endêmicas para arboviroses em Fortaleza, Brasil. Métodos: Coorte realizada entre 2018 e 2019, com mulheres entre 15 e 39 anos, moradoras em Fortaleza, Ceará, Brasil. Participaram 1.173 mulheres, usuárias de quatro unidades primárias de saúde do município. O desfecho foi categorizado em: uso continuado, uso descontinuado e não uso de repelente. Realizada análise de regressão logística multinominal norteada por modelo hierárquico, com apresentação dos respectivos odds ratio (OR) e intervalos de confiança de 95% (IC95%). As variáveis independentes incluem: dados socioeconômicos e demográficos, características ambientais e sanitárias, conhecimento sobre o repelente e aspectos comportamentais e relacionados à gravidez. Resultados: Somente 28% das participantes referiram o uso de repelente durante as duas ondas da coorte. Mulheres com escolaridade superior (OR=2,55; IC95% 1,44-4,51); com emprego (OR=1,51; IC95% 1,12-2,03); que receberam orientações por profissionais da saúde (OR=1,74; IC95% 1,28-2,36) e pela mídia (OR=1,43; IC95% 1,01-2,02); que intensificaram os cuidados contra o mosquito na epidemia (OR=3,64; IC95% 2,29-5,78); estavam grávidas entre 2016 e 2019 (OR=2,80; IC95% 1,83-4,30) tiveram as chances aumentadas para uso continuado de repelente. Conclusões: O uso de repelente entre mulheres em idade fértil mostrou-se associado a um maior nível de escolaridade, ao emprego, às orientações sobre repelente fornecidas por profissionais de saúde e pela mídia, às mudanças comportamentais de cuidado contra o mosquito durante a epidemia da Zika e à gravidez quando ocorrida a partir do início do período epidêmico.
ABSTRACT
Introducción. Aedes albopictus es un vector de arbovirus como dengue, Zika, chikungunya y fiebre amarilla. Los primeros reportes en el continente americano datan de 1985 y dada su capacidad de adaptación ecológica y fisiológica, se ha distribuido rápidamente en el territorio colombiano desde su primer reporte en 1998. Objetivo. Determinar la distribución de A. albopictus en las comunas de Ibagué, Colombia. Materiales y métodos. Los muestreos se realizaron entre mayo y noviembre de 2022 en zonas con abundante vegetación de las 13 comunas de Ibagué. Se emplearon aspiradores y redes entomológicas. Los mosquitos fueron transportados al Laboratorio de Investigaciones en Parasitología Tropical de la Universidad del Tolima para su determinación taxonómica. Resultados. Se identificaron 708 ejemplares de A. albopictus, distribuidos en las comunas de Ibagué. La mayor abundancia del vector se presentó en las comunas 10, 11, 7, 8, 2 y 9. Las comunas 3, 4, 5, 6, 12 y 13 presentaron abundancias relativas cercanas al 3 %, y la comuna 1 tuvo una abundancia del 2 %. Conclusiones. Aedes albopictus está distribuido en todas las comunas de Ibagué, probablemente su dispersión se ha visto favorecida por las condiciones ambientales y sociales de esta región. Se recomienda hacer seguimiento anual a las poblaciones de este vector y realizar una caracterización molecular de los arbovirus encontrados. Además, el conocer la distribución de este mosquito en la ciudad permitirá focalizar las estrategias de control entomológico y prevenir futuros brotes de arbovirosis.
Introduction. Aedes albopictus is a vector for arboviruses, such as dengue, Zika, chikungunya, and yellow fever. The first A. albopictus reports on the American continent date back to 1985. It has spread rapidly throughout Colombia since its first report in 1998 due to its ecological and physiological adaptation capability. Objective. To determine A. albopictus distribution in the 13 communes of Ibagué, Colombia. Materials and methods. Samples were collected between May and November 2022 in the 13 communes of Ibagué. Vacuum sampling and sweep-netting entomological nets were used in areas with abundant vegetation. The mosquitoes were transported to the Laboratorio de Investigaciones en Parasitología Tropical at the Universidad del Tolima for taxonomic determination. Results. We identified 708 A. albopictus specimens distributed throughout Ibague's 13 communes. The highest vector abundance occurred in communes 10, 11, 7, 8, 2, and 9; communes 3, 4, 5, 6, 12, and 13 had a relative abundance of around 3%, while commune 1 had 2% of relative abundance. Conclusions. Aedes albopictus is distributed throughout all the communes of Ibague. Its dispersion has probably been favored by this region's environmental and social conditions. We recommend annual monitoring of these vectors populations and molecular characterization of the found arboviruses. Ascertaining this mosquito's distribution throughout the city will enable focusing entomological control strategies and preventing future arbovirus outbreaks.
ABSTRACT
Abstract Dengue, zika, and chikungunya are arboviruses of great epidemiological relevance worldwide. The emergence and re-emergence of viral infections transmitted by mosquitoes constitute a serious human public health problem. The neurological manifestations caused by these viruses have a high potential for death or sequelae. The complications that occur in the nervous system associated with arboviruses can be a challenge for diagnosis and treatment. In endemic areas, suspected cases should include acute encephalitis, myelitis, encephalomyelitis, polyradiculoneuritis, and/or other syndromes of the central or peripheral nervous system, in the absence of a known explanation. The confirmation diagnosis is based on viral (isolation or RT-PCR) or antigens detection in tissues, blood, cerebrospinal fluid, or other body fluids, increase in IgG antibody titers between paired serum samples, specific IgM antibody in cerebrospinal fluid and serological conversion to IgM between paired serum samples (non-reactive in the acute phase and reactive in the convalescent). The cerebrospinal fluid examination can demonstrate: 1. etiological agent; 2. inflammatory reaction or protein-cytological dissociation depending on the neurological condition; 3. specific IgM, 4. intrathecal synthesis of specific IgG (dengue and chikungunya); 5. exclusion of other infectious agents. The treatment of neurological complications aims to improve the symptoms, while the vaccine represents the great hope for the control and prevention of neuroinvasive arboviruses. This narrative review summarizes the updated epidemiology, general features, neuropathogenesis, and neurological manifestations associated with dengue, zika, and chikungunya infection.
Resumo Dengue, zika e chikungunya são arboviroses de grande relevância epidemiológica em todo o mundo. A emergência e reemergência dessas infecções virais transmitidas por mosquitos constituem um grave problema de saúde pública humana. As manifestações neurológicas causadas por esses vírus têm alto potencial de morte ou sequelas. As complicações que ocorrem no sistema nervoso associadas às arboviroses podem representar um desafio diagnóstico e de tratamento. Em áreas endêmicas, casos suspeitos devem incluir encefalite, mielite, encefalomielite, polirradiculoneurite e/ou outras síndromes do sistema nervoso central ou periférico, na ausência de explicação conhecida. Caso confirmado de arbovirose neuroinvasivo é baseado na detecção viral (isolamento ou RT-PCR) ou de antígenos em tecidos, sangue, líquido cefalorraquidiano ou outros fluidos corporais, aumento dos títulos de anticorpos IgG entre amostras de soro pareadas, anticorpo IgM específico no líquido cefalorraquidiano e conversão sorológica para IgM entre amostras de soro pareadas. O exame do líquido cefalorraquidiano pode demonstrar: 1. agente etiológico; 2. reação inflamatória ou dissociação proteico-citológica, dependendo do quadro neurológico; 3. valor absoluto de IgM específica; 4. síntese intratecal de anticorpos IgG específicos (dengue e chikungunya); 5. exclusão de outros agentes infecciosos. O tratamento das complicações neurológicas visa melhorar os sintomas, enquanto a vacina representa a grande esperança para o controle e a prevenção das arboviroses neuroinvasivas. Esta revisão narrativa resume a atualização da epidemiologia, características gerais, neuropatogênese e manifestações neurológicas associadas à infecção pelos vírus da dengue, zika e chikungunya.
ABSTRACT
ABSTRACT Aedes (Stegomyia) albopictus (Skuse, 1854) was reported in Brazil for the first time in 1986 and has shown marked expansion throughout the Brazilian territory. During a routine activity to control dengue fever conducted by the Division of Entomology of the Municipal Health Department in Rio Branco city, adults and immatures of Culicidae were collected in a peri-urban area. The identified Culicidae forms indicated that they belonged to the species Ae. albopictus. This is the first official record of the presence of Ae. albopictus in the Acre State, confirming its current presence in all Brazilian states.
ABSTRACT
ABSTRACT Objectives. To characterize the distribution profile of dengue, chikungunya, and Zika virus infections in Latin America and the Caribbean and to identify possible factors associated with the risk of dissemination and severity of these arboviruses. Methods. The protocol of this review was registered on the PROSPERO platform. Searches were carried out in the following databases: Virtual Health Library, MEDLINE/PubMed, and Embase. The search terms were: Zika virus, Zika virus infection, dengue, dengue virus, chikungunya virus, chikungunya fever, epidemiology, observational study, Latin America, and Caribbean region. Studies that addressed the distribution of these arboviruses and the risk factors associated with dengue, Zika virus disease, and chikungunya, published between January 2000 and August 2020 in English, Portuguese, and Spanish, were included. Results. Of 95 studies included, 70 identified risk factors, clinical manifestations, and outcomes for arbovirus infections and 25 described complications and/or deaths. The highest frequency of confirmed cases was for dengue. Brazil reported most cases of the three arboviruses in the period analyzed. Environmental and socioeconomic factors facilitated the proliferation and adaptation of vectors, and host-related factors were reported to aggravate dengue. Most deaths were due to chikungunya, Zika virus disease caused most neurological alterations, and dengue resulted in greater morbidity leading to more frequent hospitalization. Conclusions. The review provides a broad view of the three arboviruses and the intrinsic aspects of infections, and highlights the factors that influence the spread of these viruses in the populations studied.

Mosquitoes are widely distributed around the world and carry a diverse array of viruses. Among these, mosquito-borne viruses possess the capability to replicate in both blood-sucking arthropods and vertebrate cells, rendering them significant threats to public health. For many years, the surveillance of mosquito-borne viruses mainly relied on traditional methods such as virus isolation and culture. The emergence of high-throughput sequencing (HTS) technology has not only revealed the entire spectrum of mosquito virome, but also provided a basic methodology for the rapid screening of mosquito-borne pathogens and identification of new species. Consequently, HTS has facilitated the prevention and control of mosquito-borne diseases. This review aims to describe the methods and application of HTS in the detection of mosquito-borne viruses, while also summarizing the advantages and disadvantages of HTS-based detection of mosquito-borne pathogens compared to traditional methods.
ABSTRACT
Objective:To understand the prevalence of arboviruses in mosquito samples in Xichang City, Sichuan Province, and enrich the data of arbovirus activity and genetic characteristics in southwestern Sichuan Province.Methods:In June 2018, the nucleic acid was extracted from Culex tritaeniorhynchus mosquitoes collected from different pigsties in three villages and suburbs of Xichang City. The specific primers of Yunnan orbivirus, Banna virus, Tibet orbivirus (S7, S10), Flavivirus and alphavirus were used for quantitative polymerase chain reaction examination, and the positive product was cloned for sequencing analysis. Results:A total of 9 012 mosquitoes were collected, of which Cx. tritaeniorhynchus was the dominant species. A number of 88 batches of these mosquitoes were amplified, and 2 strains of Japanese encephalitis virus (JEV), 7 strains of Banna virus (BAV), 7 strains of Tibet orbivirus (TIBOV) and 1 strain of Yunnan orbivirus virus (YOUV) were detected, respectively. By the results of cluster analysis and evolutionary tree analysis, the 17 newly found virus strains were close to the Yunnan isolates, and 2 JEV strains were located in the GI-b clade. The other 7 strains of BAV were A2 evolutionary clades. Of the 7 TIBOV plants, 6 were located in the same clade. One TOUV was in the same clade as the Yunnan strain. Conclusions:Culex tritaeniorhynchus mosquitoes in Xichang city might carry JEV, BAV, YOUV and TIBOV, among them JEV was GI-b type and BAV was A2 type. The results provide data supporting the detection and analysis of arboviruses in Xichang city.
ABSTRACT
RESUMO Este artigo apresenta reflexões sobre estratégias de educação em saúde para prevenção da Dengue, Zika e Chikungunya no âmbito do Programa Saúde na Escola (PSE), visando à atenção integral à saúde de estudantes do ensino público básico nas escolas, em parceria com as Unidades Básicas de Saúde. Trata-se de uma pesquisa nacional, oriunda de um projeto intitulado Arbocontrol, coordenado pela Faculdade de Ciências da Saúde da Universidade de Brasília, com apoio do Ministério da Saúde, com vistas ao combate e controle das arboviroses decorrentes do Aedes aegypti. De abordagem qualitativa, este estudo fundamenta-se no pensamento foucaultiano de biopolítica. Foram entrevistados 158 professores e 117 profissionais de saúde, de 16 municípios, nas 5 regiões brasileiras. Os resultados indicaram que, na execução do PSE, o saber comunitário não se incorpora nas ações. O modelo educacional conteudista estabelece, a priori, o que deve ser tratado; e a fragilidade na articulação intersetorial para o planejamento das ações tem dificultado sua eficácia. A educação em saúde ainda é entendida como processo informativo para o autocuidado, fomentado por estratégias biopolíticas de disciplinamento dos corpos dos sujeitos ou na constituição de suas subjetividades para o autocuidado, depositando neles a responsabilidade por sua saúde.
ABSTRACT This article reflects on health education strategies for the prevention of Dengue, Zika, and Chikungunya within the School Health Program toward comprehensive health care of students of primary public education in schools, in partnership with the Primary Health Care Units. This national research is nested in a project called Arbocontrol and coordinated by the Faculty of Health Sciences of the University of Brasília, with support from the Ministry of Health, to combat and control arboviruses transmitted by Aedes aegypti. This qualitative study is based on the Foucauldian thinking of biopolitics. One hundred fifty-eight teachers and 117 health professionals from 16 municipalities in the five Brazilian regions were interviewed. The results indicated that the implementation of the PSE does not incorporate community knowledge into the actions. The content-oriented educational model establishes, a priori, what should be addressed, and the fragile intersectoral articulation for the planning of actions has hampered its effectiveness. Health education is still understood as an informative process for self-care, fostered by biopolitical strategies of disciplining the bodies of subjects or establishing their subjectivities for self-care, making them accountable for their health.
ABSTRACT
A dengue é uma das arboviroses de maior incidência no Brasil e no mundo. Compreender como ela se associa a diversos fatores é de suma importância para tentar diminuir sua incidência. Dessa forma, este estudo foi realizado no ano de 2018 em bairros, tanto da zona urbana quanto da zona rural, do município de Parauapebas, no estado do Pará, com o objetivo de gerar um modelo probabilístico para descrever a probabilidade de uma pessoa do município de Parauapebas conhecer como os patógenos da doença podem ser transmitidos e sobre os sintomas da doença. Foram utilizadas técnicas estatísticas de análise exploratória de dados para descrever as variáveis utilizadas no modelo e a regressão logística múltipla, onde, de acordo com os dados obtidos, na cidade de Parauapebas, que as mulheres têm mais de duas vezes mais chance de saber os principais sintomas da doença do que uma pessoa do sexo masculino. Constatou-se ainda que uma grande parcela da população de Parauapebas não sabe como é a forma de transmissão da dengue.
Dengue is one of the arboviruses with the highest incidence in Brazil and worldwide. Understanding how it is associated with several factors is of paramount importance in trying to reduce its incidence. Thus, this study was carried out in 2018 in neighborhoods, both in the urban and rural areas of the municipality of Parauapebas in the state of Pará, with the aim of generating a probabilistic model to identify an identification of a person in the municipality from Parauapebas knows how the pathogens of the disease can be transmitted the form of dengue transmission and about the symptoms of the disease. Statistical statistics of exploratory data analysis were used to describe the variables used in the model and multiple logistic regression, where according to the data obtained, in the city of Parauapebas, women are more than twice as likely to know the major symptoms of the disease than a male person. It was also found that a person who a large portion of the population of Parauapebas does not know how the form of transmission of dengue is.

Resultados: Se notificaron 27.544 casos con el pico en 2019, siendo el 54,2% mujeres, el grupo de edad de 25 a 44 años el 36,7% y el color marrón el 70,3%. De los casos ocurridos, el 97,7% no fueron hospitalizados, el dengue clásico predominó en el 98% y se obtuvo la curación en el 99,9% de los casos. Hubo una diferencia significativa con respecto al grupo de edad y la clasificación del dengue, la hospitalización y la evolución clínica (p= 0,001). Conclusión: se evidencia que el dengue es prevalente en Anápolis, siendo necesarias estrategias de prevención y control del vector, principalmente, en los periodos de sazonalidad.

Resumo O controle ambiental do vetor no interior e ao redor dos domicílios, enquanto estratégia fundamental para a prevenção de arboviroses como dengue, zika e chikungunya, demanda um envolvimento ininterrupto da população. A pandemia de Covid-19 e, consequentemente, o isolamento social necessário ao seu controle, têm reduzido a vigilância profissional nos domicílios, tornando a atuação da população ainda mais necessária. Estudos que buscam compreender o envolvimento das comunidades na execução das ações preventivas têm sido quase exclusivamente locais. O artigo relata uma pesquisa-intervenção baseada em oficinas sobre práticas preventivas realizadas antes do isolamento social, em 16 municípios das 5 regiões brasileiras, as quais envolveram um total de 379 participantes. Os resultados apresentam as ações preventivas preconizadas por campanhas que são as mais comumente compreendidas e executadas pela população; as situações que dificultam a execução; as práticas preventivas de iniciativa própria dos cidadãos; e as práticas baseadas em saberes populares. Ficou evidente que as informações fornecidas às comunidades não podem estar restritas às campanhas de massa, e que se faz necessário investir em ações educativas mais efetivas e adequadas à variedade de contextos nacionais, com vistas a construções coletivas e intersetoriais de estratégias de enfrentamento às arboviroses.
Abstract The environmental control of the vector inside and around households, as a fundamental strategy for the prevention of arboviruses such as dengue, zika and chikungunya, demands an uninterrupted involvement of the population. The pandemic context of Covid-19, and consequently the social isolation has reduced professional surveillance in the households, making the performance of the population even more necessary. Studies that seek to understand the involvement of communities in the implementation of preventive actions have been almost exclusively local. This article reports an intervention research based on workshops on preventive practices carried out before social isolation, in 16 municipalities in the five Brazilian regions and involved 379 participants. Our results show the preventive actions recommended by campaigns that are the most commonly understood and performed by the population; situations that hinder execution; preventive practices of citizens' own initiative; and practices based on popular knowledge. It became evident that information to communities cannot be restricted to mass campaigns, and that it is necessary to invest in educational actions adequate to the variety of national contexts, seeking collective and intersectoral constructions of strategies to confront arboviruses.

ABSTRACT Aedes aegypti is the mosquito that has been most successful in adapting to the anthropic environment and transmitting several viruses to humans as well. The species has three subspecies that can identified by the variations in the color of the abdominal scales. Each subspecies possesses a distinct scale color pattern. Herein, it is described the first register of Ae. aegypti queenslandensis in São Paulo State, Brazil. Both the scale color pattern, and factor involved in the emergence of the local population are discussed, as well as possible epidemiological implications.
ABSTRACT
RESUMO O controle ambiental para a prevenção das arboviroses depende tanto de ações dos poderes públicos quanto do envolvimento das comunidades. A presente pesquisa analisou a percepção de 385 pessoas em 17 municípios das 5 regiões do País sobre a atuação das autoridades e da própria comunidade em relação ao controle e à prevenção da dengue. Independentemente da região, os participantes reconheceram que ações como saneamento básico, coleta regular de lixo, fiscalização de terrenos baldios e domicílios fechados têm sido frequentemente negligenciadas pelas autoridades. A responsabilização da comunidade, na figura do vizinho que não cumpre as medidas de controle, também foi percepção dominante, chamando a atenção a ausência de qualquer reconhecimento sobre como condições sociais desfavoráveis influenciam nas dificuldades para a realização dos procedimentos preventivos. Reflete-se ainda acerca dos prejuízos que a pandemia de Covid-19 tem causado às práticas preventivas e seus possíveis impactos futuros.
ABSTRACT The environmental control for prevention of arboviruses depends both on the actions of public authorities and the involvement of communities. The present study analyzed the perception of 385 citizens of 17 municipalities from the 5 regions of Brazil regarding the actions of the authorities and the community itself in relation to the control and prevention of dengue. The participants acknowledged that actions such as basic sanitation, regular waste collection, inspection of vacant lots and closed homes have often been neglected by the authorities. There was a tendency to hold the community accountable, through the example of neighbors who do not carry out prevention procedures. It was also noteworthy the silencing around unfavorable social conditions that can hinder the implementation of prevention procedures. We also reflected on the damage that the COVID-19 pandemic has caused to preventive practices and its possible future impacts.
ABSTRACT
A pesquisa analisa a produção de conteúdos sobre arboviroses na fanpage do Ministério da Saúde do Brasil antes, durante e após a epidemia de Zika vírus, com estudo de métodos mistos englobando análise do conteúdo divulgado entre 2015 e 2017 e o Discurso do Sujeito Coletivo (DSC) dos trabalhadores que produziam os conteúdos. Dos 5.732 posts coletados, 649 deles eram sobre arboviroses, com enfoque maior relacionado à prevenção e à Zika. O Sistema Único de Saúde (SUS) aparece em pequena parte da amostra. Há preocupação em comunicar saúde com qualidade e respaldo técnico, mas diferenças na linguagem do especialista e no timming entre o que é publicado on-line e o repassado aos serviços de saúde ocasionam ruídos. O discurso é transmissional, apresentando ausência de diálogo com a população, subestimando o potencial que a rede social tem para interação, compartilhamento e engajamento.(AU)
La investigación analiza la producción de contenidos sobre arbovirosis en la fanpage del Ministerio de Salud de Brasil antes, durante y después de la epidemia de Zika virus, con estudio de métodos mixtos englobando análisis del contenido divulgado entre 2015 y 2017 y el discurso del sujeto colectivo de los trabajadores que producían los contenidos. De los 5.732 posts colectados, 649 eran sobre arbovirosis, en un enfoque mayor relacionado a la prevención y al Zika. El Sistema Único de Salud aparece en una pequeña parte de la muestra. Existe la preocupación de comunicar salud con calidad y respaldo técnico, pero diferencias en el lenguaje del especialista y en el timing entre lo que se publica online y lo que se traspasa a los servicios de salud causan ruidos. El discurso es de transmisión, con ausencia de diálogo con la población, subestimando el potencial que la red social tiene para la interacción, compartición y compromiso.(AU)
This study analyses the content production about arboviruses on the fan page of the Brazilian Ministry of Health before, during and after the Zika virus epidemic. It uses a mixed methods study that comprises the content analysis released from 2015 to 2017 and the Collective Subject Discourse of the workers who produced the contents. The results show that 649 out of 5,732 posts collected addressed arboviruses, with a greater focus on prevention and Zika. The Brazilian National Health System (SUS) was found in a small part of the sample. There is a concern to inform about health with quality, but differences in the specialist's language and timing between what is published online and what is conveyed to technical health services cause communication noise. It is a transmissional discourse, with no dialogue with the population, underestimating the potential of social media for interaction, sharing and engagement.(AU)

Las arboviroris, son enfermedades transmitidas por artrópodos (insectos vectores), presentan una clínica habitual de fiebre, síntomas articulares, hemorrágicos y neurológicos. Los de mayor importancia en salud pública son el zika, dengue y chikungunya, y se transmiten a las personas principalmente por la picadura de un mosquito de la especie Aedes. Para resolver la falta de información en la población joven para el control y prevención de estas enfermedades vectoriales se plantea utilizar nuevas estrategias pedagógicas y tecnologías lúdicas, como los videojuegos, para una innovación educativa que promueva el aprendizaje. Se realizó una investigación descriptiva de cohorte transversal, en escolares de 5 y 6 grado, en tres colegios primarios, de la capital de la República del Perú. La muestra estuvo integrada por un total de 288 escolares y fue dividida en cuatro (4) grupos de 6 niños cada uno para la aplicación de la innovación educativa, asignados como: (ETE), (CIE 1), (CIE 2) y (CIE 3). La evaluación del conocimiento, hábitos y aceptación de los métodos se ejecutó pre y post-intervención, midiéndose mediante encuestas. Por consiguiente luego de los resultados en promedio post-intervención se concluyó que la captación de conocimientos y generación de hábitos fueron mayores para los grupos que utilizaron los videojuegos como innovación educativa lúdica, siendo el videojuego interactivo "Pica el Aedes", el que obtuvo el mayor porcentaje de aprendizaje. Sin embargo el videojuego interactivo "Pueblo Pitanga, enemigos silenciosos" fue el que obtuvo la mayor aceptación por parte de los escolares(AU)
The arboviroris, are diseases transmitted by arthropods (vector insects), they present a habitual clinic of fever, joint, hemorrhagic and neurological symptoms. The most important ones in public health are Zika, dengue and chikungunya, and they are transmitted to people mainly through the bite of an Aedes species mosquito. To resolve the lack of information in the young population for the control and prevention of these vector diseases, it is proposed to use new pedagogical strategies and recreational technologies, such as video games, for an educational innovation that promotes learning. A descriptive cross-sectional cohort investigation was conducted in 5th and 6th grade schoolchildren in three primary schools in the capital of the Republic of Peru. The sample consisted of a total of 288 schoolchildren and was divided into four (4) groups of 6 children each for the application of educational innovation, assigned as: (ETE), (CIE 1), (CIE 2) and (CIE 3). The evaluation of the knowledge, habits and acceptance of the methods was carried out before and after the intervention, being measured by means of surveys. Consequently, after the average post-intervention results, it was concluded that the uptake of knowledge and generation of habits were higher for the groups that used video games as a recreational educational innovation, being the interactive video game "Pica el Aedes", the one that obtained the higher percentage of learning. However, the interactive video game "Pueblo Pitanga, enemigos silenciosos" was the one that obtained the greatest acceptance from schoolchildren(AU)
